To all whom it may concern:

Be it known that I, JOHN LALLY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Column, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to columns and the object of the invention is to provide a column of composite construction, embodying metal and concrete the elements of which are so combined and arranged that a continuous metal sup1 ort is afl'orded throughout the entire lengt of the column 'thus adding greatly to the supporting and strain resisting properties of the column as a whole.

- A further object of the invention is to provide a novel and effective construction of cap for the column embodying braces or brackets so combined with and related to the bolts, rivets or the like.

With the above and other ob'ects in view the nature of which will more in y appear as the description proceeds, the invention consists in the novel construction,combination and arran ement herein fully described, illustrated and claimed.

In the accompanying drawings :-Figure 1 is a vertical longitudinal section through a column embodying the resent invention, showing a superimpose seated upon the column cap. Fig. 2 is a cross section through the. same on the line 22 of Fig. 1. Fig. 3 is a cross section through the same on the line 3-3 of Fig. 1'. Fig. 4 is a vertical longitudinal section through a superimposed column section, showing the manner of forming the pintle or steady pin thereon. Fig. 5 is a bottom plan view of the same. Fi 6 is a cross'section similar to Fig. 2, showm a slight modification in the construction 0 the cruciform core of the column. Fig. 7 is a detail cross section showing another way of fastening the braces or brackets in place.

The column comprises a base ,1 which under the preferred embodiment of the invention has on its upper surface an annular flan e 2 within which is received and conline the outer shell or column casing 3. This casing may be of any desired height according to the height of the column and column section,

within said casin is placed a cruciform core or main body 4 vmg the radiating wings or flanges 5 which extend outward'close .to or in contact with the inner surface of the casing 3 as indicated in Fig.. 2.

Mounted uponthe upper end of the casin 3 and the corresponding end of the centra lower annular flanges 7 and 8, respectively, the bottom flange 8 encircling the upper end of the casing 3, while the flange 7 encircles the bottom edge of the short superim osed outer casing 3, the two casing sections eing thus centered relatively to each other.

' Upon the top' of the casing section 3 is mounted a crown plate 9, the latter being formed with a series of holes in which are received the enlarged tapering heads 10 of a series of anchor bolts or rods 11, which pass downward within -the casing sections, as shown, and also through a correspondin series of holes formed in the cap rest 6, an if desired, also through a corresponding series of holes in the base 1. In case the bolts or rods 11 pass throu h the base 1, the latter is countersunk in its ower side as shown to receive and let in the nuts 12, so that a smooth even surface is provided for the bottom of the column. In some cases, however, the bolts 11 may not extend as far as the base, in which case the nuts 12 are threaded upon the bolts or rods just beneath the cap rest, as shown in Fig. 1. In this way all parts of the column are secured tied or bolted together and when the casing sections are filled with concrete as indicated at 13, a thoroughly braced, fireproof column is the result.

The crown plate 9 is eflectively braced by means of a series of triangular shaped brack-- ets 14 which reach from the cap rest to the crown plate, as shown, and each of said brackets is reduced at its inner edge to form a relatively narrow inwardly ro'ecting shank 15, the latter passing throug t e casing section 3 and havin its inner extremity bent'or extended laterally to form a hook or flange 16 which'passesbehind the adjacent anchor bolt or rod 11, the latter thus acting also as an anchor for the bracket. In reducing the bracketto form the'retaining shank 15, a shoulder 17 is formed on the bracket, said shoulder bearing against the outer side of the casing section, as-shown. In this way the brackets and casing section3 mutually brace andsupport each other.

' 'core 4 is a cap rest 6 embodying upper and, I

The {superimposed column section em-- bodies a casing 18 and a cruciform-core '19 with the arts 3 and 4 above described. 11 order to orm a connection between the two column sections, a pintle or steady in is formedon the bottom I of the superimposed column. section as shown in Figs. 1 and 4, the same.

therein, said parts corres on being adapted to fit into a corresponding socket or' seat in the cap of the lower column section, as shown in Fig. '1. In forming this pintle, a series ofbolts 21 are run lengthwise through the concrete filling'22 of the casing 18 and extended below'the lower end of'the said casin as seen in Fig. 4, while a small casing or s de jecting ends of said rods or was and led 'tions, one section extending with concrete as indicated at 24,thebolts 21 being thus firmlyembedded inthe concrete.

The pintle or steady pin 20 thus formed passes through a central opening in the crown plate 9 down into the socket provided therefor in the cap as seen in Fig. 1, thereby positioning and steadying'the u per column section and reventing the sai u per section from ti ting upon the cap. I? desired a socket 'tube 25 may be inserted in the socket opening as a lining for the same, as shown in'Fig. 1, said tube extending from the top of the crown plate to the top of the cap rest 6.

In Fig. 2 the cruciform core 4 is shown as made in one'piece, while in Fig. 6, said core is shown as made up of several ieces or seeacross the interior of the casing and 'two other narrower lates extending from the first mentioned p ate outward to'the casing. When filled with concrete all parts of'the column are" held firmly thereby. Instead of providing the hooks or'fianges 16, above described, and as shown in Fig. 3, the shanks 15 may be formed with eyes 26 to receive the bolts or rods '11, as shown in Fig. 7, the result being the same in both cases.

It will be seen that the anchor bolts or rods 11 hold or tie all parts of the column together and form a rlgid structure; further that said bolts or rods are embedded in the concrete fillin of the column and themselves effectively he d and braced at all points in their lengthv thereby. A very strong, dura ble and fireproof column is thus obtained, this being accomplished without the use of the many smallbolts, rivets and like fasteners ordinarily employed.
